'Improvements in Metal WeatherStrips, ofr

which the following is a specification.

This invention relatesv to improvementsV in that class of metallic weather-strips which are designed to be secured to thev upri ht guide-ways of window-frames for the sas es and to the stiles of said sashes, and it consists in certain peculiarities of the construction, n ovel arrangement, and operation of the va-` rious 1plarts thereof, as will be hereinafter more ily set forth and specifically claimed.

The principal object ofthe invention is to v provide weather-stri s\of the above-named character, which sha be very simple' and inexpensive and well adapted for the pur ose of preventing the passage. of air and ust, rain and moisture 1n whatever position the window-sash or other element to which the strips are applied may assume in the frame, as well `as to form guides for the movement of the sash-frames or other elements within the frame in such a manner'as` to prevent rattling and to compensate for any inequalities due to warpage or shrinkage, while requiring no es ecial skill to install them.

Variousot er objects and advantages of the invention will be disclosed in the subjoined description and explanation.

In order to enableothers skilled in the art to which my invention pertains, to make and use the same, I will now proceed to describe it, referring to the accompanying drawing, in which- Figure l1 is a horizontal sectional view ofIa portion of a window-frame and a part of the sashes thereof, showing them equipped with- 4 metallic weather-strips embodying one form of the invention; Fig. 2 is a detached perspective view of parts of the weather-stri s employedin the construction illustrated 1n Fig.

l glFig. i is a horizontal sectional view of a portion of a windoweframc and a part of one of the sashes thereof, showing said parts equi ped with a modified form of the weat er-stri s; Fig. 4 is a detached perspecf ytive view o the strips of the construction shown in Fig. 3; Fig. 5 is a horizontal, sectional view of a portion of a window-frame and a part of one of the sashes thereof, showing sald parts equipped with another modical portions 10 of iication in the construction of the strips; Fig. 6 is a detached perspective view of the Fig. 7 is a horizontal sectional view of a portion of a window-frame anda part of one of modified form of strips shown in Fig. 5, illus# trating them in the .act of being disengaged;`

the sashe's thereof, showing strips embodying i another modification applied thereto; and Fig. 8 is a detached perspective view of the strips shown in Fig. `'7 illustrating them in the another. V

V Like numerals of reference, refer to correspondin parts throughout the different views o the drawing.

` The reference numeral 1 designates a por tion of one of the uprights or si pieces of a lwindow-frame which may be provided, as usual, with a partin -stop 11, an inside-stop 12 and an outside bhnd stop 13, which sto s act of being placed inengagement with one provide runways or guideways for the si erails 14 of the sashes.

Referring now to Figs. 1 and l2 of the drawing, the reference numerall designates the main bodyor portion of one of the outside strips, that is, of one of said stri which is secured by'means of tacks or nai s 1601 otherwise, to the inner surfaces of the vertifore stated, are ro uced by the stops 11 12 and 13,' or whic gluideways may be otherwise produced.I T is main or body portlon 15 is secured vertically in the uideway therefor of the window-frame, and as at one of its edges an inturned Aflange 17pwhich is spaced from the inner surface of the part 15, and has at its other edge an inturned flange 18 which islikewise spaced from the portion 15, and is then reversed on itself as at 19 and bent outwardly to provide an extension 20 which may extend nnder the inside-stop 12 or outsidestop 13 depending on which side of the parting-stop t receiving strip, 'and as shown in Fig. 2 of the drawing, the adjacent edges of the flan es 17 and 18 are spaced apartfto receive t e 1nwardly projecting portion 21 of the inner stri which is located in a vertical groove 22 in t e outer surface. of the sash-rail 14 and the window-frame and within the guidewa s thereof, which, as be e stripsare used. This outside` strip may be properly termed the female orma be secured thereto b meansaof tacks or nai 16, or otherwise. he inner strip, as is clearly shown in Fig. 2, as welles the `outer strip, is formed of a single piece ofmetaL-and the inwardly projecting portion 21 of the inner strip is produced by folding the same up'on itself, and'has at each of its sides an outwardly extended flan e 23 to it under .1 and slidingly engage the anges 17 and 18 of the outer strip while the sides of the inwardly projecting ortion 21 will approximate or engage the adi acent edges of the flanges 17 and 18 of the outer strip.

Instead of using the strips constructed as shown in Fi s. 1 and 2 of the drawing and above-descri ed, strips ofthe construction shown in Figs. 3 and 4 may be employed, in which the construction is quite similar to that of the above-described construction, except that the flange 18 of the main or body portion 15 has the reversed portion 19 and extension 20 employed in the other construction omitted, and the inner strip has one of the outwardlyextended'flanges 23 omitted from the inwardly projecting ortion 21, as is clearly shown in Fig. 4 o the drawing.-

When this modiied construction is emloyed it-is a parent that the single outwar y extended) flange 18 on the body or main portion 15 while the inwardly rejecting part 21 'will be secured in a vertica slot 22 in the outer surface of the sash-rail by means of nails or tacks 16, or otherwise.

In Figs. 5 and 6 of the drawing is shown still another modiiication, which consists in forming the vparts of the same construction as shown in Figs. 1 and 2 and above-described, with the exception that one of the inturned ilanges on the main or body portion 15, usually the liange 18 and its reversed portion 19, is pressed closely against the part 15 instead of being spaced therefrom, as shown in Fi 1 and 2 of the drawing. In the mod cation now under consideration the inner strip is provided as in the rst abovedescribed construction with an inwardly extended vertical portion 21 produced by being A bent back upon itself and provided on each of` its sides with an outwardly extended flange 23, one of which is adapted forisliding engagement with theiange 17 and the main or body portion 15 while the other flange 23 on the inner strip is adapted to rest on the surface of the portion19 adjacent thereto, as will be readily understood by reference to 5 Aand 6 ofthe drawing.

)Iii Figs. 7 and 8 is'shown another modiied form in the construction of the weather strips, which consists in providing the outer strip with a main or-body portion 15' having at its sides inturned la es 17a and 18, the latter of which is resse closely against the inner' surface of t e portion 15a while the flange 17 is spaced therefrom, as shown. In this modified construction the extension 2O and art 19 shown .in Figs. 2 and 6 are omitted om the outer strip, and the inner strip 1s formed of the same construction as the inlange 23 will slidingly engage the' ner strip shown in Fig. 4, and has an inwardly extended vertical portion 21 provided with an outwardly extended flange 23 at one of its sides to slidingly engage the lange 17 a and part 15a while the free edge of that portion of the inwardly extended part 21 from which the flange has been omitted will lie in close proximity to the depressed lange'18a and on the inner surface thereof.

Ineach of the constructions the inwardly extended portion 21 of the inner strip is fitted in a vertical groove 22 in the outer surface of the sash 14,' and may be secured in place by means of tacks or nails 16, 'orotherwisa and as before stated, the outer strip 1n any of the constructions may also be 'secured to the inner surface of the window-frame by means leXibilitand slight resiliency of the weatherstrips. urthermore, it will be obvious that as the strips embodying the, invention are adapted for sliding engagement with one another air, dust, moisture and water will be labsolutely excluded or shut out. Furthermore, it 1s apparent that vby using the con--4 structions shown in Figs, 3 and 4, as well as in Figs. 7 and 8, the weather-strips may be detached from one another by removing the sashes inwardly or'outwardly from the parting-stop 11, which can be done by simply re-l moving the inner stop 12 or the outer stop 13, when said strips embodying saidconstructions are employed on both. .of the,

sashes, and it is Vmainlyl to permit such removal of the sashes an such disengagement Vof the strips that one of the lan es 23 is omitted from` lthe inner strip as s own in Figs. 4 and8, and mainly for alike'purpose are the parts 18 and 19 1n Fig. 6 and 18 in Figs, 7 and 8 pressed against the fparts 15v and 15a, respectively.

In some instances the inner portion-21 of the inner strip may be simply located'in the groove of the sash-rail without being secured therein, and one or both ,of the anges 23 may be secured to the i'ianges of the outer piece, thereby permitting the sash to be. moved on the inwardly extendedportion 21 of the inner strip. 1

. Having thus fully described my invention, what I claim alsnew, and desire to secure by Letters-Patent, is- 1. In a weather strip, the combination with an outer strip consisting of a piece of sheet metal adapted to be secured vertically or longitudinally to a suitable 'support and having an inturned flange at each of its side edges, one of said flanges being spaced from the main body of said stri v, of an inner stri` consisting of a sheet meta piece 'formed wit a vertically disposed inwardly extended por tion adapted to be secured vertically` or lon itudinally to a support and having on eac side of its portion adjacent to the outer strip an outwardly extended flange one of which flanges is adapted tol underlie one of 'said flan es on the outer strip and to slidingly engage t e saine.

2. In a weather-strip, the combination with an outer strip consisting of a piece of sheet metal adapted to be secured vertically or longitudinally'to a suitable support and having at one of its side edges an inturned flange provided with a reversed portion and outward extension and at its other side-edge with an inturned flange, of an inner str1 consisting of a sheet metal piece formed wit a vertically disposed inwardly extended portion adapted to be secured vertically or longitudinally to a movable support and having on each side of its outer portion an outwardly extendedilange.

3. In a weather-strip, the combination with an outer strip consisting of a piece of sheet Inetal adapted to be secured vertically or longitudinally to a suitable support and having an inturned flange at each of its side edges, one of said flanges having an outwardly reversed portion provided with an outwardly projecting extension, of an inner strip consisting of a sheet metal piece formed with a vertically disposed inwardly extended ortion adapted to be securedvertically or ongitudinally to a movable support and having on each side of its outer portion an outwardly extended flange one of which 1s adapted to underlie one of the flanges on the outer strip and the other of which is adapted to overlie the other flange on said strip.
